Status of the MADMAX Experiment

Relic axions generated after cosmic inflation may have a mass of around 100 μeV. While being an excellent candidate for cold dark matter, axions of this range are hardly covered by existing detection techniques, which are based on electromagnetic resonance of 3D cavities. A dielectric haloscope is a promising alternative technique for a search in this mass range. The MADMAX collaboration is aiming to build a dielectric haloscope that is sensitive to post-inflation QCD axions. Here, we present the principle, current status, and future plans of the MADMAX experiment.
